Service base
Oilfield service firms such as Halliburton (about 1,400 staff in Odessa) and Baker Hughes are major local employers.
Midland and Odessa are neighbouring West Texas cities that serve as the main service and headquarters base for the Permian Basin. Winters are cool to mild but lows reach freezing or below on about 58 mornings a year, so equipment must handle both heat and occasional frost. An intrinsically safe mobile phone distributor in Midland and Odessa, Texas would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Midland and Odessa, Texas has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Midland and Odessa, Texas: Compressor stations, Gas processing plants, Wellsites and tank batteries | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Midland Odessa. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Oilfield service firms such as Halliburton (about 1,400 staff in Odessa) and Baker Hughes are major local employers.
The semi-arid setting has hot, sunny summers and cool, dry winters with strong winds. Crews often drive long distances between sites.
Midland and Odessa began as railroad stations halfway between Dallas and El Paso on the Texas and Pacific line, sit about 20 miles apart and are jointly promoted as Two Cities, No Limits.
The surrounding Permian Basin is about 250 miles wide and 300 miles long and contains more than 7,000 fields, so sites are spread across a very large area.
The Permian Basin oil boom of the 1920s moved the area's economy from cattle to energy, and by 1929 a total of 36 oil companies had set up offices in Midland.
Activity follows energy cycles, and the 2015-16 oil downturn and the 2020 pandemic both depressed local activity, so contractor availability and demand can change quickly.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Midland and Odessa, Texas. Field crews drive long distances between wellsites, tank batteries, compressor stations and gas plants, then carry a phone into the classified area. An intrinsically safe handset is designed for that pattern, so a technician can log readings and take photographs on site. Certification must be finished before any Zone 1 use.
A distributor for Midland and Odessa, Texas would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are wellsites and tank batteries, drilling rigs, compressor stations, gas processing plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Midland and Odessa, Texas.
It has been, for example the lowest US unemployment rate in 2014, and it moves with oil prices. Plan for competition for experienced technicians and book service or training slots with enough notice.
Midland has a hot semi-arid climate with roughly 115 afternoons above 90 degrees Fahrenheit a year, plus dust. Choose devices with a dust-tight rating, check the operating temperature range, and keep them out of parked vehicles in summer.
Crews often drive long distances between sites in a semi-arid setting with hot summers and strong winds. A rugged IP68 handset and a managed fleet help, and a vehicle charger would stay in safe areas. Battery performance in heat should be checked, and offline operation tested where coverage is patchy.
